The study of eccentric bunghole self-positioning system based on computer vision technology

This paper on the basis of deeply understanding the domestic automatic filling equipment's, develops an eccentric bunghole selfpositioning system based on computer vision technology, through full automatic camera calibration and improved Hoff conversion algorithm to obtain the coordinate information of circle centre of eccentric fillers, thus controls the operation of driving stepper motor, realizes the automatic positioning of sprue guns to eccentric bunghole. The experiment proves the operation accuracy of this system is high, the speed is fast, the algorithm is efficient, stable, and a high practical value.
